Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The present invention provides a kind of mobile terminal and refers to the computer equipment that can be used on the move, including but not limited to hand
Machine, notebook, tablet computer, POS machine, vehicle-mounted computer, camera etc..
Also referring to Fig. 1 and Fig. 2, as shown, mobile terminal includes display screen 10, nonmetal parts 20 and metal back cover
30, metal back cover 30 is installed on the side in the non-display face of display screen 10.Specifically, metal back cover 30 includes metal base plate 302
With metal sidewall 304, metal sidewall 304 is connected to the edge of metal base plate 302, and metal sidewall 304 and metal base plate 302
It is integrally formed, metal sidewall 304 is that 302 edge of metal base plate extends outwardly and is bent to form.In a kind of embodiment, metal side
Wall 304 is equipped with buckle or other fixed structure (not shown)s, and metal back cover 30 by itself and is shown by metal sidewall 304
Display screen 10 is fixed to each other.Nonmetal parts 20 are between metal back cover 30 and display screen 10, specifically, nonmetal parts 20 are installed on
On display screen 10, and nonmetal parts 20 are the plane being bonded with metal back cover 30 in face of the surface of metal back cover 30.It is nonmetallic
A variety of electronic components are additionally provided with inside part 20, electronic component is electrically connected with system board.Display screen 10, nonmetal parts 20, metal
The assembling of rear cover 30 forms mobile terminal, and display screen 10 shows that image, nonmetal parts 20 carry the electricity that mobile terminal realizes each function
Device inside mobile terminal is isolated from the outside world by road system, metal back cover 30, while keeping mobile terminal overall appearance beautiful, new
Grain husk.
In the present embodiment, metal base plate 302 includes a pair of of the long side 3022 and a pair of short edges 3024 being oppositely arranged, a pair of short
Side 3024 is oppositely arranged and is connected between a pair of of long side 3022.In a kind of embodiment, metal base plate 302 is rectangle, certainly,
Metal base plate 302 or other shapes.Further, the quantity of metal sidewall 304 is two and is connected to one
To in long side 3022, after metal back cover 30 is installed on display screen 10, nonmetal parts 20 are contained in metal base plate 302 and metal

It sees, is novel.
Please refer to Fig. 3 and Fig. 4, nonmetal parts 20 are equipped with groove 200 in face of the surface of 30 side of metal back cover, after metal
Lid 30 covers the notch of groove 200 and forms resonant cavity with groove 200.Specifically, nonmetal parts 20 face metal back cover 30
Surface be bonded with metal back cover 30, i.e., metal base plate 302 cover groove 200 notch and with groove 200 formed resonant cavity.
Nonmetal parts 20 are additionally provided with holding tank 220, and antenna radiator is placed among holding tank 220, antenna radiator and nonmetal parts
Electronic component inside 20 is electrically connected with signal transmitting and receiving module, and sends and receives signals work.The low frequency of antenna radiator transmitting-receiving
Double resonance occurs in resonant cavity for electromagnetic wave signal, increases the bandwidth of low frequency signal.Further, design resonant cavity is different
Length a, width b and thickness, change the size of resonant cavity, can control the variation of resonance frequency, wherein cavity
Thickness is the depth of groove 200.Specifically, the size of resonant cavity is related with the size of mobile terminal, it is for length
140mm-150mm, width 70mm-80mm, with a thickness of the mobile terminal of 7mm-8mm, the length a of cavity 65mm-80mm it
Between change, width b is in 50mm-70mm, and when with a thickness of 5mm-7mm, the resonant state of resonant cavity is best, and low frequency signal is in resonance
Double resonance occurs for cavity, and low frequency bandwidth increases.
Fig. 5 and Fig. 6 is respectively the typical S11 parameter schematic diagram of the mobile terminal of resonance free cavity and setting resonant cavity,
The size of S11 coefficient has reacted the size of return loss, when trough occurs in S11 coefficient curve, illustrates the echo damage at trough
Consume the resonant state small, the signal of frequency separation where antenna system can receive and dispatch trough, i.e. antenna assembly have the frequency.It is right
Than the S11 parameter curve of two kinds of situations, when resonance free cavity, the resonance frequency of low frequency signal is 824MHz~929MHz, low frequency
Bandwidth is about 105MHz；When resonant cavity is set, the optimal double resonance shape that is obtained by adjustment length a, width b and thickness
The resonance frequency of state, low frequency signal is 731MHz~1013MHz, and low frequency bandwidth is about 282MHz, and low frequency bandwidth significantly increases, and
And there are two troughs it is seen that S11 parameter curve has, i.e., caused by generation double resonance.
Low frequency signal generation double resonance is mentioned to increase low frequency bandwidth by forming cavity body structure in the terminal
The low frequency signal receptivity of high mobile terminal promotes the speech quality of user, meets outlet run in early stage to compatible multiband
The demand of signal.
In the present embodiment, metal base plate 302 is equipped with multiple openings, for camera, the fingerprint across the mobile terminal back side
Key range or other devices.Certainly, in other embodiments, camera and fingerprint recognition key also can be set mobile whole
On other positions at end, the scope of the invention cannot be limited thereby.
In the present embodiment, nonmetal parts 20 are plastics, glass or ceramic material.
In a kind of embodiment, the system board of mobile terminal is installed between nonmetal parts 20 and display screen 10, non-gold
200 depth of groove for belonging to part 20 is identical as the thickness of nonmetal parts 20, i.e. groove 200 is practical for through the logical of nonmetal parts 20
Hole, when through-hole is rectangle, 20 section of nonmetal parts is the structure of hollow, the metal bottom of the inner wall of through-hole, metal back cover 30
Plate 302 and system board constitute resonant cavity.20 processing method of nonmetal parts of the structure is simple, and cavity body structure makes low frequency signal
Double resonance occurs and improves the low frequency signal receptivity of mobile terminal to increase low frequency bandwidth, promotes the call matter of user
Amount meets the needs of outlet run in early stage is to compatible multi-band signal.
Above disclosed is only several preferred embodiments of the present invention, cannot limit the power of the present invention with this certainly
